I agree with MJtru I think I'll re build the bottom do the basics good head gasket arp studs and bigger oil pump and bigger sump, new timing belt water pump. Just leave it standard too begin with and upgrade turbo and comp :-)

No point in spending big bucks to rebuild rb25 back to standard - don't waste your money... Either throw in a rb30 bottom end or just get a second hand motor and throw it in your car.

I would like to follow this and see what he does. Drifting you will need to rebuild that old RB30 in no time. If it's not already shot. Well one good leason I've learned if any is. The most expensive idea I ever got was a free one much less a free engine. The 30 could work, all in saying is you will never know the health of the components in that rb30 block. Please keep us posted mate. I would like to know what you did. Both options can work, just work with new parts in them that's all I'm saying. Me personally I would go back with rb25.

If the ringlands are gone then chances as the bore a scratched so it depends if the damage can be bore out or not, on the other hand if the cheap or free RB30 block just needs a hone and rings and bearing then RB30>RBless capacity any day of the week and twice on Sunday

And the RB30 is an easier fit in to a R33 GTS-t then any GTR and plenty of GTR owners ( me included ) haven't gone to the trouble of fitting them for no reason

I have a "drifter" and everytime I look at it and how it was treated and look at how much his previous owners poured into him and I think WHY!!! I'm hoping to bring "Bashful" back to his former glory!!! Love my car even tho secretly I think he wants to kill me

Toys are not just for boys!!!

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
